概要	Multi-source field notes is a data collection approach in which two or more observers, sites, or vantage points contribute written records of naturally occurring events, interactions, and settings. By pooling notes from multiple sources, researchers cross-check individual impressions and capture aspects of a scene that any single observer would miss, strengthening descriptive richness and analytical trustworthiness.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
